The magnetic force microscopy (MFM)[1]}, [2]}, [3]}, [4]}, [5]} and polar magneto-optic Kerr effect (MOKE) microscopy[6]}, [7]} are commonly utilized for the visualization and analysis of spin texture stability and dynamics. For MFM, Co-alloy coated tip scans across the sample surface at lift heights of 20-30 nm, ‘sensing’ the spin textures based on the tip-sample interactions. Tips with super sharp profile (diameter \(\sim \) 30 nm) and ultralow magnetisation (80 emu/cm\(^3\) ) are typically used to provide high resolution imaging with mimimal stray field perturbations. Meanwhile, polar MOKE utilizes the rotation of the polarisation of an incident beam of linearly polarised light to elucidate the magnetic structure of the sample, with a resolution limited by the wavelength of light used (\(\sim \) 300 – 500 nm). While MFM is capable of visualising both IP and OP domain characteristics, polar MOKE enables high throughput characterization of PMA materials. Concomitant in-field imaging and electrical manipulation of spin textures can be carried out by custom designing the MFM and polar MOKE set-up to integrate magnets and electrical instruments e.g. pulse generator, amplifier and oscilloscope, and associated circuitry.[2]}, [5]}
